RE: Scope for a Muzzle Loader
I had a pine ridge on one for while. But it wouldn't hold POI for somereason. After shooting and getting zero'd, I would clean with boiling hot water, and all that cleaning knocked it out. I now got a Leupold Vari X III 1.5-5 and never have problems.
If your shots are under 75 yards and you don't care about 2MOA changes, go with the cheapy Pine ridges.
